20 Pb Radius vs Neutron Star RadiusThe 208Pb radius constrains the pressure of neutron matter at subnuclear densities.The NS radius depends on the pressure at nuclear density and above.Most interested in density dependence of equation of state (EOS) from a possible phase transition.Important to have both low density and high density measurements to constrain density dependence of EOS.If Pb radius is relatively large: EOS at low density is stiff with high P. If NS radius is small than high density EOS soft.This softening of EOS with density could strongly suggest a transition to an exotic high density phase such as quark matter, strange matter, color superconductor, kaon condensate…PREXUVa Seminar, Nov 2005R.
